RESEARCH AND DEVELOPMENT ON TUNNEL LININGS IN THE UNITED STATES
VERSUCHS- UND ENTWICKLUNGSARBEITEN MIT TUNNELAUSKLEIDUNGEN IN DEN USA
Research has been carried out on polymer concrete which has 4 to 5 times the strength of conventional concrete and greater resistance to fire (fires in tunnels, prefabricated tunnel lining segments). Regulated-set cement is used and handling time is from 10 to 40 minutes. (70 km/cm square compressive strength and 20 km/cm square flexural strength 90 minutes after mixing). Steel fibre reinforced concrete is used as pumped or projected concrete for structural support (115 kg of 0.025/0, 55/25 mm fibre per cubic meter of concrete, or 5% of total weight, 10 mm maximum granulation and 120 kp/cm square flexural strength). Tests have been carried out on tunnel lining on a 1/1 scale.
